I own four QSC K8s (and the associated mounting yoke), as my surrounds/rears.
With the mounting yoke, they can be aimed in any direction necessary. And I've mounted them on a Uni-Strut system, whereby I can move them individually, or as a group of two (sides or rears) as needed to align perfectly with whatever seating config I need.
Since my room is a non-dedicated space, my seating config has changed a time or two. Currently, it's somewhat locked in, but you never know.
It worked out well.
Typical of any decent pro two way, they're powerful.
I got the K8 due to the wide coverage pattern more suited the environment and listening distance. The entire K series are 1kw, active, DSP with every conceivable connectivity option (even built in mixer!).
iirc, they use Celestion drivers.
Here's a few images;

And the phase plugs seen down behind screen in the CD throat;
The coverage of the horn is mated to the size of the LF driver, the aim was to assure there's no gross irregularities in directivity.
Before I mounted them, I used three up front, in LCR duty, ... they were surprisingly a wonderful performer. I've detailed my findings somewhere here at AVS.
IMO, they're a solid value.
